Two days after making available the 3D printer files for the first 3D printed gun the number of downloads for the firearm has hit 100,000. After Defense Distributed’s Cody Wilson test fired the weapon the 3D design files were hosted on defcad.org for anyone to download.

Forbes have reported that the “Liberator” gun plans have been ten times more popular than the groups other gun related 3D print plans, which include large capacity magazines and automatic rifle “receivers”.

“This has definitely been our most well-received download,” says Haroon Khalid, a developer working with Defense Distributed. “I don’t think any of us predicted it would be this much.”

Much of the download traffic was facilitated by Kim Dotcom’s Mega storage site as users are prompted by the Defcad.org website to download a collection of CAD files from there. The Liberator design files have also found their way onto filesharing site the Pirate Bay within their new 3D printing file section.

Forbes reports that the U.S. leads the way in Liberator downloads, followed by Spain, Brazil, Germany and then the U.K. It should be noted that it’s probable that only a small number of users will try and print the gun, and then only a very small number will own a 3D printer that is capable of producing a fireable weapon. For the gun that successfully fired Cody Wilson used a Stratasys Dimension SST 3D printer bought off eBay for $8,000, which is out or reach for most home hobbyist printers.

The popularity of this project is also reflected in the high number of visitors to Defence Distributed’s website, over 550,000 in two days, and the 3 million views the following YouTube video has garnished.
